Abstract Wheat germ is a valuable by-product of the wheat milling process, represents 10-15% lipid contents with other bioactive compounds. Various wheat germ oil (WGO) recovery methods have been adopted, including mechanical pressing, solvent extraction, and supercritical fluid extraction.
Why is germ removed during the milling process?
During the milling process of wheat, its germ is removed to increase the shelf-stability of flour, which can be compromised by the rapid degradation of germ due to the presence of enzymes (i.e., lipoxygenase and lipase) and a high content of easily oxidised unsaturated oils.
Can defatted wheat germ be fermented using Lactobacillus plantarum?
Summary This study explored the fermentation of defatted wheat germ (DWG) using Lactobacillus plantarum, leading to the release of bioactive peptides with improved technological and health properti…
How to recover wheat germ oil?
Various wheat germ oil (WGO) recovery methods have been adopted, including mechanical pressing, solvent extraction, and supercritical fluid extraction. Some modifications reported by different experimental studies to enhance the oil yield retain the nutritional attributes of fresh oil.
